Happily married but still haunted by an unresolved love affair from her past, choreographer Alicia searches through the depths of her memories to create Siren, a new dance piece about unfulfilled desire. Against the backdrop of an aging theatre by the sea, Alicia builds a sensual and naked ensemble work that is delicately held together by the threads connecting her dancers with each other and with her. She soon finds herself falling down the rabbit hole of her own creation, in love with the male lead dancer, Giovanni, as the siren of her fictional work slowly becomes the siren of her life. When Alicia recounts this story to Karl, his own story brings a new dimension to this exploration of desire and artistic creation. Written on Water is a sensual and philosophical interrogation of the permeable boundaries between fiction and reality, muse and siren and the changeable roles we play - Odysseus, sailor, siren - in our lifelong quests for connection, love, and inspiration.
